Those who love a hot cup of coffee in the morning will appreciate this awesomely unique heat sensitive mug from ECOSCO. Simple in design, this mug features a black background with a design of a battery with bright green energy bars.
What makes this product so unique is that the mug is actually heat sensitive, and when hot drinks are poured in, the energy bars will actually light up displaying to the drinker that the cup is hot. This is a fantastic way to tell whether your beverage is hot or cold depending on how many colored energy bars are displayed.
